Search the Internet for a list of prime numbers - the Wikipedia article on prime numbers might list a few. All numbers between 2-100 that are not prime, are composite. (The number is not counted as prime, nor as composite.)

The composite factors of 100 are 4, 5, 10, 20, 25, 50, 100

Let's try 99 and 98! 99 is 3 x 3 x 11 and 98 is 2 x 7 x 7 98 and 99 are consecutive numbers, composite numbers, less than 100 and there is no prime numbers between them!

1, which is 2 b/c all of the other even numbers are divisible by 2, therefore making it composite.

All composite numbers have more than 2 factors but prime numbers have only 2 factors

The sum of these composite numbers, including 100, is 3989.The sum of all numbers between 1 and 100 is 5,050. From this we need to subtract the sum of 1 plus all the prime numbers below 100. The sum of the primes is 1,060. Subtracting (1 + 1060) or 1,061 from 5,050 yields 3,989.

1, which is 2 b/c all of the other even numbers are divisible by 2, therefore making it composite.

The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, 100 2 and 5 are prime. 1 is neither. The rest are composite.

1 is special 2 prime 3 prime 4 composite 5 prime 6 composite 7 prime 8 composite 9 composite 10 composite 11 prime 12 composite ext.

The set of even numbers contains the prime number, 2. The set of composite numbers contains infinitely many odd numbers.

All even numbers are composite, because 2 is a factor of every even number.
